You want your child to eat healthy foods, but do you know which nutrients are necessary and in what amounts? Here's a quick overview of nutrition for kids.

Nutrition for kids is based on the same principles as nutrition for adults. Everyone needs the same types of nutrients — such as vitamins, minerals, carbohydrates, protein and fat. Children, however, need different amounts of specific nutrients at different ages.

So what's the best formula to fuel your child's growth and development? Check out these nutrition basics for girls and boys at various ages, based on the 2010 Dietary Guidelines for Americans.

Fruits. Encourage your child to eat a variety of fresh, canned, frozen or dried fruits — rather than fruit juice. If your child drinks juice, make sure it's 100 percent juice and limit his or her servings.
